Wound infections account for the most frequent postoperative complication.
Additionally burst abdomen is observed in 1 to 3 % of the patients within the first days after a midline laparotomy. 
We have to take into consideration that the incidence of incisional hernias 12±1 months postoperatively is estimated to be up to 20 % (range 9 to 20 %). 
Consequently, the problem of the therapy of the incisional hernia is not sufficiently solved, considering that up to every second patient suffers a relapse after its closure (range 30-49 %). 
Studies show that the Abdominal Wall fascia requires approximately two months to regain 50 % of its original strength. 
Extra-long term reliability is needed to facilitate a correct healing of the Abdominal Wall fascia.
